摘要：

The use of the boundary elements technique permits precise evaluation of the acoustic pressure field diffracted by barriers of different shapes on a flat ground. Absorption conditions on the ground and the barrier may be included easily. Different examples are investigated and excess attenuations obtained by shape changes are compared.
